Description of problem: I'm testing the following script: ==================================== # cat mod.stp probe module("ext3").function("*") { printf("%s\\n",probefunc()) } ==================================== Runnning this script writes names of functions correctly as expected, but when you try to terminate it with ctrl+C, the kernel crashes (probably). When I tested it, my sessions hang and I was unable to log in with another ssh session. After some time the boxes were awaken again, rebooted. Nothing unusual was in /var/log/messages. It may possibly be a kernel bug, stap bug, or both. Version-Release number of selected component (if applicable): systemtap-0.7.2-2 kernel-2.6.18-92 How reproducible: always Steps to Reproduce: 1. create mod.stp as above 2. stap -V mod.stp 3. after a while, hit ctrl+C Actual results: hang Expected results: correct termination Additional info: This doesn't occur on 2.6.18-124 kernel.
